## Clone the repo
```bash
# change location to the path you want Infisical to be installed
cd ~
# clone the repo and cd to Infisical dir
git clone https://github.com/Infisical/infisical
cd infisical
```
## Set up environment variables
Before running the docker-compose we have to generate the .env file with the environment variables, you can create your own file or start with the
`.env.example` as an example guide.
Mandatory variables in the `.env` file:
1. Keys and JWT variables

The `.env.example` has these variables empty, you can self generate the `JWT and ENCRYPTION_KEY` with this [32-byte random hex strings generator](https://www.browserling.com/tools/random-hex).
For the `PRIVATE_KEY and PUBLIC_KEY` you can use the ones shown in the screenshot:
```
PRIVATE_KEY='oGVv5rThrpZ7WLgQW27chY1cXngr4wLQIZnGfSKgHPk='
PUBLIC_KEY='ldr6JaC7AY+tun3omGLdE4SWpkJbtVBOI54KfUP53Xc='
```
2. Mongo variables and site URL
![image](https://user-images.githubusercontent.com/118568289/206792171-3376e3c6-c3ac-4d5d-8776-d78ee089b520.png)
These variables are used to connect the MongoDB and set the URL for the localhost.
For development, you can use `root` for the `MONGO_USERNAME` and `example` for the `MONGO_PASSWORD` as shown in the screenshot.
Take into account that if you use your own `MONGO_USERNAME` and `MONGO_PASSWORD`, you also have to change the `MONGO_URL` with the form of `MONGO_USERNAME:MONGO_PASSWORD` after the `//` part of the URL.
3. Mail SMTP service variables
![image](https://user-images.githubusercontent.com/118568289/206792653-ba3211d1-1071-43f2-93a7-8b408bbd9e0e.png)
These variables are needed to use the Mail SMTP service that takes care of sending the verification code when you
register in the app.
For the `SMTP_USERNAME` variable, you will need an email with 2-steps-verification.
For the `SMTP_PASSWORD` variable, you will need to [generate an app password](https://support.google.com/mail/answer/185833?hl=en) with the email you used in the `SMTP_USERNAME` variable.
With this environment variables, you will be ready to run the docker-compose.
## Docker for development
```bash
# build and start the services
docker-compose -f docker-compose.dev.yml up --build --force-recreate
```
Then browse http://localhost:8080
```bash
# To stop environment use Control+C (on Mac) CTRL+C (on Win) or
docker-compose -f docker-compose.dev.yml down
# start services
docker-compose -f docker-compose.dev.yml up
```
The docker-compose development environment consists of:
- nginx
- frontend
- backend
- mongo
- mongo-express
